Maximum advisable time to put on earmuffs

[abunickabhi]

I generally put my earmuffs on for the entire day. I use it for my MBLD attempts, workplace (to focus and code), travelling (to avoid horns and shouting) and during online chess to focus better. The non-cubers and people unacquainted with earmuffs feel that excessive use is dangerous. I feel it does not matter and is not a health hazard even in the long term.
I use non-electronic 3M X series earmuff which is comfortable even when I am running, sweating or in an extreme temp humidity environment. I have used 3 models of earmuffs in the past 12 years extensively and have not faced any problem.

Variable factors which make answering this question precisely impossible:

• Temperature and Humidity varies from room to room, city to city
• Our ear canals need airing to stay healthy
• Everyone's ear, hygiene and earmuff size are different
• We can efficiently use our mouth more to compensate for the blocked ears

I think always wearing earmuffs is probably not very good
but how much is too much as you said depends on a lot of things
I personally wear earmuffs some of the time while I do my schoolwork, most of the time while I do bld events or clock solves with 7-simul and whenever it gets particularly loud as I have a lot of siblings who can be quite noisy at times.
I have not found any issues with the amount of time I spend wearing earmuffs
the earmuffs I use are 3M Folding Earmuff 90563 Black my mum bought them for me right before I last competed
